ok here is my take from another tall guy. active workout days should be at min 3 days a week. consider doing core, and cardio work like p90x whit what else it may need.
i am at 286 from 332 roughly so i can say that fitday helped kick start the engine but what has helped the most after that was Water and 2% milk.
i am a SLYGUY still durning summer
